I run growth at Wispr Flow, so I spend most of my time deep in AI tools and automation. I'd been following Fryderyk and the Zeta Labs team since Jace, their AI email assistant, and was impressed by how fast they shipped product. When Fryderyk showed me Viktor, it clicked immediately. I'd been spending hours building automations in Claude Code - stitching together context, writing scripts, trying to make things persistent and scheduled. Viktor did all of that natively. It just lives in Slack, already has the context from your tools and conversations, and runs on its own. But the thing that genuinely blew me away was the proactive behavior. Viktor doesn't just wait for you to ask. It observes how your team works, chimes in when it spots something relevant, and suggests automations you didn't think to set up. I've never seen an AI tool take initiative like that. I ended up advising the team on growth strategy because I believe this is how every team will work within a few years. Not another tab. Not another tool. A coworker that lives where your team already communicates. If you're skeptical, give it your worst task. That's what convinced me.
